Influence of Cu on the mechanical properties of an Al-4.4wt%Mg alloy after ECAP
(Trans Tech Publications, Ltd., 2006)
Two Aluminium alloys, type AA5182 and AA5182+1.2wt% Cu, have been studied. The
second alloy in solution treated condition is 18% stronger than the first one. During ageing at 150°C or 200°C it shows a characteristic fast ...
Biaksijalna metoda igle za obrađivanje sposobnosti drapiranja tkanina od agroceluloznih vlakana / Biaxial pin method of determination the agro cellulose woven fabrics drape ability
(Savez inženjera i tehničara tekstilaca Srbije, 2004)
Razvijena je metoda za ispitivanje sklonosti tkanina ka drapiranju, nazvana metodom igle. Metoda se zasniva na oceni drapiranja uzoraka tkanih površina pravougaonog oblika. Metoda omogućava simultano određivanje faktora ...
Fermentation of wheat and triticale hydrolysates: A comparative study
(Elsevier Sci Ltd, Oxford, 2009)
In bioethanol production four wheat varieties were investigated: NS 40S, Renesansa, Rapsodija and Dragana, as well as four triticale varieties: Oganj, Jutro, Odisej and NST 21/06. The samples were grinded and mixed with ...
An intensity based optical fiber sensor for low velocity impact detection in unidirectional composites
(Taylor & Francis Ltd, Abingdon, 2000)
Prevention df serious damage of composite structures might be achieved by inspecting the structural integrity during exploitation. This paper decribes the design and development of a promising optical fiber sensor system ...
Effect of hydrogels based on 2-hydroxyethyl methacrylates to erythrocyte resistance to hemolysis
(Belgrade : Institute of Technical Sciences of SASA, 2007)
In this study hemolytic activity of hydrogels different chemical construction and
synthesized under different conditions was examined. The hydrogels are synthesized by
radiation and chemical polymerization of 2-hydroxyethyl ...
Recycled Wool Based Non-Woven Material as Sorbent for Heavy Metals
(University of Minho, Portugal, 2001)
The aim of this study was to investigate the sorption properties of recycled wool based non-woven material for heavy metal ions. To improve sorption properties wool material was treated with air low-temperature plasma (LTP) ...
Application of the residual strength degradation model to carbon-epoxy composite
(Consultants Bureau/Springer, New York, 2008)
A residual strength degradation model for two orientations of fibers of carbon-epoxy composite is proposed. The model is constructed on the basis of an analysis of a gradual decrease in the residual strength of the composite ...
Characterization of nano-powder morphology obtained by ultrasonic spray pyrolysis
(Savez inženjera metalurgije Srbije, Beograd, 2008)
Spherical nanosized particles of copper were synthesized by ultrasonic dispersion of solutions from copper sulphate in the temperature range of 800-900°C in hydrogen atmosphere. A controlled particle size was realized ...
The influence of residual stresses on welded joints and other inhomogeneous materials with cracks / Uticaj zaostalih napona na ponašanje zavarenih spojeva i drugih nehomogenih materijala sa prslinama
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2009)
Residual stresses in many structural components are often produced during the fabrication or bonding processes, due to the cooling from elevated temperatures. Examples for such behavior are: welded and soldered joints, ...
